[Emc-users] Max speed too fast
Stephen asked: |Is there any particular reason why you chose 2,400,000 for the servo and |traj periods? I'm sure it will work for these speeds (and it does |reduce the CPU load marginally), but it shouldn't be necessary to |lengthen these. Can you share your reason for changing them? Stephen, In answer to your question: I spent a few hours doing the old only change one thing at a time routine and I found that as I brought base period below 10,000 even slightly, the display started to slow down and the cursor became sticky. By 8000 it was freezing up the machine. I decided that even if it worked at 1 a little margin wouldn't hurt as long as I could get the number of steps per second I needed. Hence 12,000 I juggled the servo and traj from a high of 5,000,000 down to 1,000,000. I was getting some real time errors at 1,000,000 and they seemed to go away at around 3,000,000 but as I went towards 5,000,000 I started getting following errors when I had the display (TK) in continuous mode but not in any of the incremental modes. When I lowered servo and traj periods down to 3,000,000 the following errors stopped. (note that I didn't say it stopped because I lowered it) Again a little margin Hence 2.5 but 2,400,000 is a nice multiple of 12,000 so why not use it since it was arbitrary anyway. In my trials I always left the traj and servo the same even though it's probably not necessary and I might try changing each independently but I don't know what would be the gain since it seems to be behaving pretty well now.

Re: [Emc-users] Pumakins module missing
To use the puma kinematics, you need to compile the complete development version of emc2, not just pull a few files from the development version and add them to your installed version. You can compile the development version without disturbing any of the files from your installed version. Instructions are located on our wiki: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_5_10_and_6_06_from_source Jeff - This SF.net email is sponsored by: Splunk Inc.

Re: [Emc-users] Pumakins module missing

I downloaded the puma config files, and located them according to the instructions. When I load emc with the puma configuration it fails with a message that says: HAL:4: ERROR: Can't find module 'pumakins' in /usr/realtine-2.6.15-magma/modules/emc2 I'm a little confused, I can find the pumakins.c file and pumakins.h files in the cvs, but putting them in that directory dosn't help. I'm assuming that I need to compile these two to get a pumakins module. I'm not sure how to do that. Any help would be greatly apreciated. Jeff already replied to this, but I'm going to explicitly spell out something that he only implied in passing. Pumakins is NOT part of the currently released EMC (version 2.1.7). It is relatively new, and is in the CVS (development) version only. It will be part of EMC version 2.2.0 when that is released (probably sometime this fall). If you want to use it now you need to get the development version from CVS. As Jeff already said, you do NOT want to mix and match code from two different versions, that way lies madness. Jeff already posted a link to instructions for getting and compiling the CVS version. Leave your installed version alone, and compile the CVS version using run-in-place.

Re: [Emc-users] Interactive machining
Hi Recently I found job as a CNC programmer with leader aerospace manufacturers. We use Catia 5 . Our parts are very complex (5 axis surface machining) and expensive and it is difficult/impossible to just go into the program and adjust something. That kind manual adjustment can cause machine to crash and it is expensive mistakes! If something need to be change ? somewhere undercut than need go back to Catia and redo programming. My conclusion is that need keep standard core G code clear out of any ?Script Innovations?. EMC must be able smoothly use code generated by main CAD-CAM programs. Today already and into the future all commercial machining will be complex ? complex part to be made- that CAD-CAM becomes more and more important. New type of interactive programming is good but it must be as separate software and never bundle with any EMC release. Aram - This SF.net email is sponsored by: Splunk Inc.

I would like to use it to compile a new component. Thanks. I think you need a full checkout to use comp. Comp is really a preprocessor that outputs C code, which is then compiled like any other component. It's necessary to use the same compiler and settings when compiling a component, so distributing comp separately would be a chore, I think. If you follow the instructions on the wiki here http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_5_10_and_6_06_from_source, you should be able to get things going.

Thanks to them who developed it!). Just install the emc2-dev package using synaptic and you will be ready to write and compile your new HAL components!
